Cytokinesis is less complex than mitosis because it is simply the splitting of the cytoplasm to produce two daughter cells or two new cell membranes. It only follows the sequential phases that mitosis have. Mitosis is a continuous process which has four sequential phases namely, prophase, metaphase, anaphase, and telophase. Mitosis is the complete splitting of the cell involving much more processes than cytokinesis including the interphase and DNA replication.
During exocytosis, vesicles in the cell fuse with the cell membrane, releasing their contents to the outside. It involves the movement of an intra cellular vesicle to the plasma membrane, then fusion.There are many cellular processes that involve exocytosis. These include:1.release of neurotransmitters from presynaptic neurons2. secretion of enzymes, peptides hormones and antibodies from cells.3. Placement of integral membrane proteins4. Antigen presentation during an immune response.5. acrosome reaction during fertilization.6. Recycling of plasma membrane bound receptors
